AI Technical Summary
In existing condenser structures, corrosion of the delivery pipe can lead to leaks that contaminate dry air, posing a health hazard, especially in medical applications, and also result in low condensation efficiency.
An S-shaped cavity and multiple parallel channels are set inside the plate-shaped shell. The two ends of the delivery pipe extend out of the shell and are connected by a U-shaped pipe to form an S-shaped structure, which slows down the airflow speed, prevents refrigerant leakage and contamination of dry air, and improves condensation efficiency.
It effectively prevents leakage of the delivery pipe from contaminating the dry air, improves the condensing efficiency of the condenser, and promptly prompts for maintenance or replacement to ensure the quality of the dry air.

TECHNICAL FIELD
[0001] The utility model relates to a condenser, especially a condenser structure for producing dry air which is composed of a plate-shaped shell, a cover plate and a conveying pipe placed in the plate-shaped shell. BACKGROUND
[0002] A condenser structure for producing dry air is disclosed in the market, which comprises a plate-shaped shell, a cover plate and a conveying pipe placed in the plate-shaped shell. An S-shaped cavity for facilitating gas passing through is arranged in the plate-shaped shell between the plate-shaped shell and the cover plate. An air inlet and an air outlet are arranged in the cavity. A condensed water outlet is installed at the bottom of the cavity. Since the conveying pipe is arranged in the S-shaped cavity, the outer surface of the conveying pipe is in contact with air. Therefore, when the conveying pipe is corroded and leaks, the produced dry air is easily contaminated. Especially, when the dry air used in the medical industry is contaminated, it is easy to cause harm to the human body. SUMMARY
[0003] The utility model aims at providing a condenser structure for producing dry air and a manufacturing method thereof, which can not contaminate the produced dry air when the conveying pipe is corroded and leaks, and improve the condensing efficiency.
[0004] To achieve the above-mentioned purpose, the utility model provides a condenser structure for producing dry air, which comprises a plate-shaped shell, a cover plate and a conveying pipe placed in the plate-shaped shell. An S-shaped cavity for facilitating gas passing through is arranged in the plate-shaped shell between the plate-shaped shell and the cover plate. An air inlet and an air outlet are arranged in the cavity. A condensed water outlet is installed at the bottom of the cavity. An S-shaped cavity is arranged on one side of the plate-shaped shell in the thickness direction. A plurality of channels for placing the conveying pipe are arranged on the other side of the plate-shaped shell in the thickness direction, which are parallel to each other. The S-shaped cavity is separated from the plurality of channels. The two ends of the channels are respectively communicated with the two side surfaces of the plate-shaped shell in the length direction or the width direction. The two ends of the conveying pipe placed in the channels respectively extend out of the plate-shaped shell.
[0005] The plane formed by the plurality of channels is parallel to the plane formed by the S-shaped cavity.
[0006] One end of the conveying pipe arranged in the channel is connected to one end of the conveying pipe in the upper channel through a U-shaped pipe. The other end of the conveying pipe in the channel is connected to the other end of the conveying pipe in the lower channel through a U-shaped pipe, forming an S shape, and the U-shaped pipe is placed outside the plate-shaped shell.
[0007] The height of the bottom layer of the S-shaped cavity placed below the air inlet is greater than the height of each layer of the S-shaped cavity, so as to slow down the passing speed of the airflow.
[0008] The width of the vertical cavity placed below the air outlet is greater than or equal to the height of the bottom layer of the S-shaped cavity, so as to slow down the passing speed of the airflow.
[0009] With this structure, because the S-shaped cavity is arranged on one side of the inner thickness direction of the plate-shaped shell, a plurality of passages parallel to each other are arranged on the other side of the inner thickness direction of the plate-shaped shell, the S-shaped cavity is separated from the plurality of passages, the two ends of the passages are communicated with the two sides of the plate-shaped shell in the length direction or the width direction, and the two ends of the conveying pipe placed in the passages respectively extend out of the plate-shaped shell. When the conveying pipe is corroded and leaks, the refrigerant will flow from the gap between the conveying pipe and the plate-shaped shell to the outside, without polluting the produced dry air, and the staff can be reminded to repair or replace the structure in time. In addition, because the height of the bottom layer of the S-shaped cavity arranged below the air inlet is greater than the height of the other layers of the S-shaped cavity, the airflow passing speed is slowed down. The width of the vertical cavity arranged below the air outlet is greater than or equal to the height of the bottom layer of the S-shaped cavity, so that the airflow passing speed is slowed down. Therefore, the condensation efficiency is improved. BRIEF DESCRIPTION OF DRAWINGS
